Add fetch timeout and unify logging on stdout

- Abort the Anthropic fire request after FIRE_TIMEOUT_MS instead of
  letting it hang indefinitely with no outcome logged.
- Log info and error levels both to stdout (JSON has a level field
  already) so a single log stream/tail shows the full picture instead
  of splitting across stdout/stderr, which was hiding forward failures
  from anyone only watching one of the two.
